The ALPHA 78 is a self-contained, high frequency linear
power amplifier capable of
continuous operation at input powers in excess of two
kilowatts PEP/SSB and one
kilowatt average or continuous carrier, with no time limit.
It is manually tunable
from 1.8-2.0 plus 3-22 MHz, optimized for convenience in the
160 through 15 meter
amateur bands (export models also cover 10 meters).
Four additional bandswitch positions provide NO-TUNE-UP
operation at full legal
power on the 80 through 15 meter amateur bands. The ALPHA 78
is capable of high
speed break-in CW (QSK) when used with a transmitter or
transceiver of suitable
break-in capability. The ALPHA 78 also incorporates a
feature permitting optimization
of efficiency in either the CW or "phone" subband when using
the NO-TUNE-UP
feature on 80/75 through 15 meter amateur bands.
